Swing Bolt & Flange Design
Swing Bolt & Flange Design
(OP)
Hello!
I've to design a vessel that has a body flanged top head (see attachment). There are to be 8 swing bolts that will fix the head to the rest of the vessel for operation. Design conditions are 4/-1 Barg, 180/0 Deg C, 1370mm ID.
I really dont know where to begin with this design. We have PV Elite 2011 & Codecalc in house but i'm not sure if these can help my design.
Would be great if i could get a few pointers in the right directions.
Thanks a mill.

You won't get much help from Codecalc.
Interesting all the modelling that goes on these days, apparently in advance of design.

They do a lot of closures.

RE: Swing Bolt & Flange Design
The PV Elite will help you design the vessels itself, using the girth flange design as Appendix 2 with normal flange. Then you design the swing bolts, components like bolt in shear and bending, lugs, slot design in top flange, etc. There are the swing bolt manufacturers who will give you advice how to design the bolts, since that's their bread and butter. They can help you with lug design, pin design, etc.

If you don't know where to start now then you are better off finding someone who knows what they are doing. For instance it looks like you are welding the lower lugs across a circumferential weld seam. Not advised and probably not allowed depending on your code.
